Market Size & Premium Growth
In 2024, U.S. P&C insurers wrote about $1.05 trillion in direct premiums, an increase of 8.0% from the year before, marking the first time the industry exceeded the $1 trillion threshold. These property and casualty insurance industry statistics reflect sustained demand for both personal and commercial lines, driven by rising property values, broader adoption of insurance products, and rate increases following years of underwriting pressures.
Premium growth has been particularly strong in personal lines such as auto and home insurance, where rate increases have helped insurers cover higher claim costs and inflationary pressures. Meanwhile, commercial lines continue to grow steadily as businesses expand and face new liabilities.
Premium Growth Trends by Line of Business
Personal lines have led the recovery, with segments like private auto achieving notable improvements in underwriting and combined ratios. For instance, in 2024, private auto posted a net combined ratio of 95.3%, a dramatic improvement from over 112% in 2022.
Homeowners insurance also saw improved profitability, with a net combined ratio of 99.7%, the first result below 100 since 2019. Even commercial segments showed resilience, though liability and multi‑peril lines continue to face higher loss costs.
Underwriting Performance in the Property and Casualty Insurance Industry Statistics
After recording underwriting losses in 2023, the U.S. P&C industry posted a $22.9 billion net underwriting gain in 2024, a dramatic turnaround from the $21.2 billion underwriting loss in 2023. This marked the first underwriting profit since 2020 and signaled a broader shift toward sustainable underwriting practices.
AM Best’s reports highlight that the improvement was supported by a 5.0 percentage point improvement in the combined ratio, which fell to 96.6% in 2024 from over 101% in 2023 which was the best industry result in over a decade.
The industry’s positive trend continued into 2025. According to AM Best, the U.S. P&C sector reported $11.2 billion in net underwriting income for the first half of 2025, up significantly from about $2.9 billion in the same period of 2024. At the same time, the combined ratio improved to 96.4%. Catastrophe losses accounted for roughly 10.9 percentage points of that ratio, up from around 8.8 points the prior year. These gains are consistent with recent property and casualty insurance industry statistics.
Broader 2025 Performance Signals: Nine‑Month Results
Extending beyond the first half, underwriting performance continued to strengthen through the first nine months of 2025. According to AM Best, the industry achieved a $35 billion net underwriting gain through nine months, compared to a $4 billion gain in the prior year period. The combined ratio improved to about 94.0% overall, aided by relatively moderate catastrophe activity in mid‑to‑late 2025.
This sustained improvement highlights how the industry is better managing risk and underwriting outcomes, even as external pressures like climate events continue to test capacity.
2025 Property and Casualty Insurance Industry Statistics and Beyond
The U.S. P&C insurance industry is well-positioned for growth but must navigate ongoing challenges:
- Softening personal auto markets may pressure rates, particularly with rising costs of electric vehicle repairs and advanced driver assistance systems.
Commercial lines must adapt to social inflation, evolving broker dynamics, and global economic pressures. - Opportunities exist in AI adoption, telematics-based auto insurance, and customizable commercial policies, enabling insurers to deliver better value and operational efficiency supported by current property and casualty insurance industry statistics.
At HealthSure Hub, we monitor these trends to provide stakeholders with actionable insights and highlight the importance of innovation and disciplined underwriting.
